The research results indicate that the qualities of the Jurassic reservoir are dominated by construction. Good reservoirs lie to an advantaged nose protrusion, nearly relating to the distribution of sedimentary micro-facies. The reservoir that lies on the main position in the riverway has better gathering characters. Because argillaceous content is increase and the porosity and permeability became smaller, the character of the reservoir becomes bad in the flood plain area that lies on the skirted riverway and between riverways. Characters of the layer relate to the distribution of main sand-body that the better feature of the layer and the bigger thick of sandbody layer.

通过综合储层含油性、非均质性、分类研究的GIS 分析结果，研究认为：长西油田侏罗系储层性质受构造控制，储集性好的储层在区域上大多属于一个有利的鼻状隆起；且与沉积微相的展布密切相关，在河道主体部位的储层其储集性一般都较好，而在河道侧缘和河道之间的泛滥平原沉积区，泥质含量增加，孔渗性变差，储层的储集性也变差；储层优劣与主砂带的分布也有关，砂层厚度越大，储集性越好。
